The study of biology has greatly benefited from recent advances in microfluidics due to many reasons, such as the ability to leverage the small scale of microfluidic channels in order to organize and study cells in a manner that closely models the spatial organization found in the body. Along with my supervisor, Prof. Edmond Young, we designed and fabricated a 3D microfluidic system that further improves the advantages of working at microscale and the flexibility of using microfluidic designs. Our main objective was to replace various poly (dimethylsiloxane) (PDMS) structures that represent cell interfaces within microfluidic devices with a more representative material, like a hydrogel.
With the generous support from ESROP and valuable guidance from Prof. Young, I have gained experience in engineering design, microfluidics, microfabrication, basic cell culture, microscopy and programming from cell analysis. As a side project, I had the opportunity to perform some programming from cell image analysis. It is very fortunate to acquire a wide range of skills and experience in creating and analyzing a microfluidic system that has biological applications.
Aside from the rewarding research skills, this summer has given me an opportunity to meet and get to know different students (graduate and PhD students) and professors. I experienced an important part of university with which I was less familiar with before the start of the summer. I had the opportunity to see the development of Professor Young’s laboratory of Integrative Biology and Microengineered Technologies (IBMT) in its early stages. I think it is especially rewarding to work in our lab during my summer because when new materials and equipment arrived and were installed, we learned to use them and troubleshoot together. This was a great learning experience for everyone in our lab. I thank Division of Engineering Science and ESROP for generous support and my bright supervisor Professor Young for this unforgettable summer.
